Description

  The present invention relates to a game machine provided with optical decoration means.

  For so-called arcade game machines installed in commercial facilities such as game shops, decoration effects and eye catching effects are indispensable to attract players, and for this reason, ornaments with various tastes have traditionally been used for game machines. Has been added.

  However, in order to ensure the stability of the casing of the game machine, there are certain restrictions on the size and arrangement of the ornament. In particular, the height direction may be greatly limited by the height of the ceiling or entrance of the game store. On the other hand, facilities with high ceilings are also increasing, and in such facilities, the game casings appear relatively small, and the decoration effect and eye catching effect are impaired.

  Therefore, an object of the present invention is to provide a game machine that can fully utilize the upper surface side of a housing as a decoration space.

  The present invention solves the above-described problems by the following means. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  The present invention includes a housing (5), a framework (11) provided so as to project obliquely upward from the upper surface of the housing, a screen (12) attached to the surface of the framework, and the screen The above-described problem is solved by a game machine provided with projection means (23) for projecting a predetermined image toward the screen.

  According to the present invention, by providing a screen on the upper surface of the housing and projecting an image, various images, designs, patterns, etc. can be displayed on the screen to enhance the decoration effect and eye catching effect of the game machine. it can. Since it is a simple structure that attaches a screen to the framework, it can be made lighter than a movable structure, etc., so even if the area is increased, the center of gravity of the chassis is kept low, and the stability of the chassis Can be secured sufficiently. In addition, since the structure is simple and lightweight, it is easy to remove the framework and screen from the housing if they are in the way when they are brought into a store or the like. It can be attached to show the original decoration effect and eye-catching effect.

  In the present invention, the screen is provided so as to protrude obliquely upward from the casing in front of the casing, and the projection means is provided at a lower portion on the front side of the casing with the projection direction facing upward. May be. In this case, a sufficient distance can be secured between the projection means and the screen, and a large image can be projected on the screen.

  In the present invention, the subunit (3) separable from the casing may be arranged on the front side of the casing so as to surround the projection means and not overlap the optical path of the projection means. If the subunits are arranged in this way, the subunits can be made to function as protection means that prevent a player or the like from entering the optical path of the projection means.

  In the game machine of the present invention, frame support means (15, 17) for supporting the framework in a state in which the inclination with respect to a horizontal plane can be changed may be provided on the upper surface of the housing. By changing the inclination of the framework, the height of the screen can be adjusted according to the height of the ceiling of the place where the game machine is installed or the height of the entrance / exit.

  The frame support means includes a frame support plate (15) attached to an upper surface of the casing in a state of being vertically and parallel to the front-rear direction of the casing, and the frame support in a state in which an inclination with respect to a horizontal plane can be changed. A frame holder (17) attached to a plate, and a lower end portion of a vertical frame constituting the framework is inserted into a hollow portion between the frame support plate and the frame holder, and the framework is It may be supported on a housing. According to such an aspect, the framework can be attached to the upper surface of the housing at various angles simply by changing the inclination of the frame holder with respect to the frame support plate.

  As described above, according to the present invention, it is possible to enhance the decoration effect and eye catching effect of the game machine by displaying various images on the screen arranged on the upper surface of the housing. Since the structure is simple and the weight can be easily reduced, the area of the screen can be increased to enhance the decoration effect and the like, while the center of gravity of the casing can be kept low to ensure sufficient stability of the casing. In addition, since the structure is simple and lightweight, it is easy to remove the framework and screen from the housing if they are in the way when they are brought into a store or the like. It can be attached to show the original decoration effect and eye-catching effect.

  1 to 3 show an embodiment of a game machine to which the present invention is applied. FIG. 1 is a front view, FIG. 2 is a plan view, and FIG. 3 is a right side view. As is apparent from these drawings, the game machine 1 is set in a commercial facility such as a game store, and is a commercial game machine (so-called arcade game) that provides a game within a predetermined range as consideration for the consumption of economic value by a player. The main unit 2 and three subunits 3 arranged at the front center, front right side, and front left side of the main unit 2, respectively. Each subunit 3 can be separated from the main unit 2 and installed at an appropriate position. The consumption of economic value in the game machine 1 is performed by inserting medals into the subunit 3.

(Main unit configuration)
As shown in detail in FIGS. 4 to 6, the main unit 2 has a housing 5 that can stand on a floor of a store or the like. The casing 5 is configured using wood or a resin material in the same manner as a normal game machine. A monitor 6 is installed on the left side of the front of the housing 5, and a lottery machine 7 is installed on the right side of the monitor 6. For the monitor 6, a large display such as a liquid crystal projector or a plasma display is preferably used. Of course, a liquid crystal display or CRT may be used as a monitor. The lottery machine 7 will be described later.

  The casing 5 of the main unit 2 is provided with various decorations in order to enhance the decoration effect of the game machine 1. For example, a decoration 8 is provided outside the monitor 6 and the lottery machine 7. Similarly, a sail 10 is provided on the upper surface 5 a of the housing 5 in order to enhance the decoration effect of the game machine 1. As shown in FIGS. 5 and 6, the sail 10 includes a framework 11 and a screen 12 stretched on the surface of the framework 11. The framework 11 is configured by combining a plurality of vertical frames 13 and horizontal frames 14. On the other hand, the screen 12 is made of, for example, a white vinyl cloth or canvas. The screen 12 is fixed to the surface of the framework 11 so that moderate slack occurs between the vertical frames 13. Various means may be used for fixing the screen 12.

  A cover 5 b that hides the lower portion of the sail 10 is fixed to the front edge of the upper surface 5 a of the housing 5. On the back surface side of the cover 5b, a plurality of frame support plates 15 are erected in parallel with the front-rear direction of the housing 5 and spaced vertically along the left-right direction of the housing 5 (left-right direction in FIG. 1). Arranged in a state. These frame support plates 15 are fixed to the upper surface 5a and the cover 5b of the housing 5 by using bolts 16, respectively. A frame holder 17 is attached to each frame support plate 15. In FIG. 6, the frame holder 17 is hidden behind the two frame support plates 15 on the near side and is not visible.

  As shown in detail in FIG. 7, the frame holder 17 opens one side surface of a cylindrical body having a quadrangular cross section, and flanges 17a (only one side is shown in FIG. 7) are provided on both edges of the opening. It has a configuration. The frame holder 17 is fixed on the frame support plate 15 by screwing bolts 18 attached to the flanges 17 a into the frame support plate 15. By combining the frame holder 17 with the frame support plate 15, an elongated cavity portion is formed between the frame support plate 15 and the frame holder 17, and the lower end portion of the vertical frame 13 is inserted into the cavity portion. 10 is attached on the housing 5 in a state of being tilted so as to protrude toward the front side of the game machine 1 toward the upper end.

  The frame support plate 15 is provided with a plurality of screw holes 19 into which bolts 18 attached to the lower end side of the frame holder 17 are to be screwed. These screw holes 19 are arranged along an arc having a constant curvature radius centered on a fulcrum set on the upper end side of the frame holder 17. Although not shown, screw holes corresponding to the bolts 18 attached to the upper end side of the frame holder 17 are also arranged along an arc having a constant curvature radius centered on the fulcrum. However, regarding the upper end side, any one of the screw holes may be used as a fulcrum when the inclination angle of the frame holder 17 is changed. Therefore, by changing the screw hole 19 into which the bolt 18 is screwed, the inclination of the frame holder 17 can be changed, and thereby the inclination angle of the sail 10 can be changed. Further, if the vertical frame 13 is extracted from the frame holder 17, the sail 10 itself can be separated from the housing 5.

  As shown in FIGS. 4 to 6, a light box 20 is provided at the lower end on the front side of the housing 5. As shown in FIGS. 8 and 9, the light box 20 has a closed cabinet 21 and can be separated from the housing 5. The upper surface 21a of the cabinet 21 is inclined obliquely, and a transparent panel 22 is provided on a part of the upper surface 21a over almost the entire length of the light box 20 in the width direction (corresponding to the left-right direction of the housing 5). A projection device 23 is arranged inside the cabinet 21 so as to face the transparent panel 22. The projection device 23 is for projecting a pattern or the like printed on the slide 24 with illumination light from the light source 25, and the projection direction is set vertically upward. As is clear from FIG. 5, the light box 20 is disposed on the front side of the housing 5 so that the transparent panel 22 is positioned directly below the sail 10. Thereby, the illumination light of the projection device 23 can be received by the screen 12 of the sail 10 and an image such as a design of the slide 24 can be projected onto the screen 12. FIG. 10 shows an example. The image projected on the screen 12 may be a still image or a moving image. The slide 24 may be omitted, and a dynamic effect may be performed on the screen 12 by changing the color or pattern of the illumination light from the light source 25.

  1 to 3, when the subunits 3 are arranged around the housing 5, the positions of the subunits 3 are set so as not to overlap the optical path from the projection device 23 to the screen 12. The Then, since each subunit 3 surrounds the light box 20, there is no possibility that a player or the like enters the optical path from the projection device 23 to the screen 12.

  11 and 12 show the main part of the lottery machine 7. As shown in FIG. 11, the lottery machine 7 includes a cabinet 30, a drum 31 disposed on the front side of the cabinet 30 so as to be capable of turning around a longitudinal axis, and an indicator 32. A ball passage 33 is provided around the drum 31. As shown in FIG. 10, the surface of the drum 31 is divided into eight equal parts in the circumferential direction, and numerals 1 to 8 are displayed in each region.

  As shown in FIG. 12, a ball throwing mechanism 34, a drum drive motor 35, an indicator drive mechanism 36, and a ball collection mechanism 37 are provided inside the cabinet 30. The ball throwing mechanism 34 throws a lottery ball B (see FIG. 11) into the ball passage 33 in response to a throwing command given to the lottery machine 7 by the control system of the game machine 1. The drum drive motor 35 rotates the drum 31 around its axis. The indicator drive mechanism 36 monitors whether or not the ball B is thrown into a pocket 38 provided immediately below the drum 31 so as to be continuous with the ball passage 33. When the ball B is thrown into the pocket 38, it is detected. In response, the indicator 32 is moved from the horizontal standby position P1 shown in FIG. 11 to the operation position P2 raised vertically. The tip of the indicator 32 is formed in a needle shape, and can selectively indicate any one area on the drum 31 at the operating position P2.

  The ball B thrown into the pocket 38 is guided to the ball collection mechanism 37 through the duct 39. The ball collecting mechanism 37 returns the ball B to the ball throwing mechanism 34. For example, the ball B passed from the duct 39 is conveyed vertically upward by a toothed belt 37a traveling in the vertical direction, and the upper end of the belt 37a is turned up. The ball B is configured to pass to the ball holding portion 34a of the ball throwing mechanism 34 near the position.

  The lottery machine 7 as described above is provided for selecting any one of the numerical values 1 to 8 provided on the drum 31, and its function is realized as follows. First, when a lottery start instruction is given to the lottery machine 7 from the control system of the game machine 1, the drum drive motor 35 is driven accordingly to start the rotation of the drum 31, and subsequently the ball is thrown into the ball throwing mechanism 34. When the command is given, the ball B is thrown into the ball passage 33. When the thrown ball B reaches the pocket 38, the indicator driving mechanism 36 is driven and the indicator 32 is driven to the operating position P2. The drive motor 35 is stopped. The numerical value indicated by the tip of the indicator 32 after the drum 31 is stopped is specified from the rotational position of the drum drive motor 35 (for example, detected by an encoder), and any one of 1 to 8 is determined as the numerical value selected by lottery. Is done. The ball B in the pocket 38 is returned by the ball collection mechanism 37 in preparation for the next lottery. The front side of the lottery machine 7 is covered with a transparent cover to prevent the ball B from jumping out. The lottery probability may be changed by changing the temporal relationship between the timing when the ball B reaches the pocket 38 and the timing when the drum 31 stops within a range that the player does not notice. Such an operation can be used for adjusting the payout rate, for example. The lottery machine 7 is not limited to the above configuration as long as any numerical value can be selected, and the configuration may be changed as appropriate.

(Subunit configuration)
Next, the subunit 3 will be described with reference to FIG. In addition, since the structure of the three subunits 3 is mutually equal, the one subunit 3 is demonstrated below. As shown in FIGS. 13 to 16, in the subunit 3, the two right and left stations 40 are integrated on a single casing 41. The station 40 is a minimum unit of a place where a player plays a game. As apparent from FIGS. 1 and 3, the height of the casing 41 of the subunit 3 is not hidden from the main part 2 of the monitor 6 and the lottery machine 7 (including the drum 31 and the pocket 38). It is so limited. Although a medal hopper device for holding and paying out medals is provided inside the housing 41, the illustration thereof is omitted.

  Returning to FIGS. 13 to 16, a game space 42 is provided in the upper portion of the housing 41, and a game board surface 43 is formed for each station 40 on the bottom side of the game space 42. Details of the game board surface 43 will be described later. A medal payout device 44 shared between the stations 40 is arranged between the game board surfaces 43. In order to prevent the player from accessing the game board surface 43, the game space 42 is covered with a transparent cover 45 (shown opaque in FIGS. 14 to 16). A control panel 46 is provided on the front side of the housing 41. The control panel 46 is provided with a pair of left and right medal throwers 47 for each station 40. The medal insertion device 47 is a device that rolls and inserts a medal as a game medium in a vertical state, and its tip is inserted into the game space 42 through the cover 45. In order to enable adjustment of the insertion direction of medals according to the player's intention, the direction of the medal insertion unit 47 can be adjusted at least in the left-right direction. For such a medal inserter 47, a well-known medal shoot commonly used in a so-called pusher game may be used.

  The control panel 46 is provided with a push button type operation switch 48 for each station 40. The operation switch 48 is operated, for example, in order for the player to instruct the timing of throwing the ball B by the lottery machine 7. Of course, the operation switch 48 may be provided for other purposes.

  The control panel 46 is provided with a medal tray 50 for each station 40. The medal tray 50 is provided as a payout destination for medals acquired by the player. Details of the medal tray 50 are shown in FIGS. 17 and 18. The medal tray 50 is formed by processing a metal material such as a stainless steel plate, and has a rectangular bottom wall 51, a front wall 52 disposed around the bottom wall 51, left and right side walls 53, 54 and a rear wall 55. have. The side walls 53 and 54 are provided with flanges 53 a and 54 a for attaching the medal tray 50 to the housing 41. A folded portion 52a is formed at the upper end of the front wall 52 toward the outside.

  In order to enable the player to take out medals, the upper surface side of the medal tray 50 is opened, and the height of the front wall 52 is set sufficiently lower than the other walls 53 to 55. However, as apparent from FIG. 18, the front wall 52 has a function of preventing the medal M from falling to the front of the medal tray 50 and holding the medal M stacked on the bottom wall 51. . Therefore, it is desirable to set the height of the front wall 52 as large as possible within a range that does not hinder the removal of the medal M. However, when the bottom wall 51 has a sufficient area, the front wall 52 is not necessarily required. The front wall 52 may be omitted by attaching a slope that rises forward to the bottom wall 51.

  The left side wall 53 is provided with a slit-shaped medal payout port 53b that is long in the vertical direction for paying out the medal M into the medal tray 50 so as to be closer to the rear wall 55 side than the front wall 52. An L-shaped cover 56 is provided at the upper end of the rear wall 55 so as to extend so as to hide the medal payout opening 53b. Further, the rear wall 55 is provided with a protruding portion 57 extending over almost the entire length in the width direction of the medal tray 50 (a direction orthogonal to the paper surface in FIG. 18). The protruding portion 57 is disposed above the bottom wall 51 so that a space for receiving the medal M is formed between the protruding portion 57 and the bottom wall 51. Further, the protruding portion 57 is formed in a tapered shape that becomes narrower in the vertical direction from the base portion joined to the rear wall 55 toward the tip. Such a protrusion 57 is provided by bending a plate material into a V shape and joining it to the rear wall 55. However, the protruding portion 57 may be formed by various methods such as a drawing material and casting. The position of the projecting portion 57 is set directly below the medal payout opening 53 b, and the tip thereof substantially coincides with the tip of the cover 56. Further, the lower end position of the projecting portion 57 substantially coincides with the upper end of the front wall 52. Further, a curved wall 58 having an arcuate cross section is provided between the bottom wall 51 and the protruding portion 57.

  According to the medal tray 50 as described above, the medals M paid out from the medal payout port 53b into the tray 50 are dropped onto the bottom wall 51 and stacked while being guided by the protrusion 57. Since the projecting portion 57 is provided on the rear wall 55, there is no possibility that the medal M is stacked while leaning against the rear wall 55 as indicated by an imaginary line M 'in FIG. For this reason, as indicated by an imaginary line L1 in FIG. 18, the piles of medals M stacked on the bottom wall 51 spread almost uniformly from the apex portion in the front-rear direction of the tray 50 (the left-right direction in FIG. 18). The medals are not easily jammed around the medal payout opening 53b without any action from the player, and a relatively large number of medals M can be stored in the medal tray 50. If the protrusion 57 does not exist, the medals M ′ leaning against the rear wall 55 are stacked as they are. As a result, the medals M descend from the rear wall 55 toward the front wall 52 as indicated by an imaginary line L2. They are piled up so as to form a gradient, and the area around the medal payout opening 53b is quickly clogged. Therefore, the number of medals M that can be stored in the medal tray 50 without correction by the player is smaller than that of the medal tray 50 of the present embodiment.

  Next, the details of the game board surface 43 will be described with reference to FIGS. The configuration of each game board surface 43 is common, and one game board surface 43 will be described below. As shown in FIG. 19, on the game board surface 43, a monitor 60, a medal payout outlet 61, an upper table 62, and the like from the upstream side (corresponding to the back side) to the downstream side (front side) in the medal flow direction. A medal guide device 63, a checker 64, and a lower table 65 are provided. The monitor 60 is provided as display means for executing a game at each station 40 and performing various effects. The medal payout outlet 61 is disposed directly below the monitor 60. The medals sent out from the medal hopper device in the housing 41 to the medal guide 66 are paid out from the medal payout opening 61 toward the upper table 62. The upper table 62 is provided so as to be movable between a horizontal position indicated by a solid line in the drawing and an operating position lifted upward as indicated by an imaginary line in the drawing with the front end edge 62a as a fulcrum.

  20 to 24 show details of a portion from the upper table 62 to the lower table 65. A medal guide plate 67 is provided above the lower table 65. The medal guide plate 67 is transparent, and two medal guide plates 67 are provided in each station 40 so as to have a 1: 1 correspondence with the medal inserter 47. 20 and 21, only the medal guide plate 67 corresponding to the medal inserter 47 on the right side is shown. As apparent from FIGS. 22 and 24, the medal guide plate 67 is provided with a downward slope toward the back side of the game board surface 43 (the side where the monitor 60 is provided) and the center side in the left-right direction. The medal M inserted from the medal inserter 47 rolls on the medal guide plate 67 and falls onto the medal guide device 63 while changing its direction toward the center according to the gradient of the medal guide plate 67. The medal guiding device 63 guides the medal M to the checker 64 while aligning the direction of the medal M in the front-rear direction of the game board surface 43, and details thereof will be described later.

  The checker 64 is fixed at a fixed position on the game board surface 43, and a large number of slit-shaped medal passage holes 64a are provided on the upper surface side thereof. The medal passage hole 64 a extends in the front-rear direction of the game board surface 43. The medals M that have dropped from the medal guide device 63 onto the checker 64 are classified into those that pass through the medal passage hole 64a and those that do not pass through the medal passage hole 64a according to the dropping position. The medal M that has passed through the medal passage hole 64 a is taken into the checker 64 and returned to the medal hopper inside the housing 41. On the other hand, the medal M that has not passed through the medal passage hole 64 a falls to the lower table 65.

  Although not shown, a large number of medals are placed on the lower table 65 in a stacked state. A pusher 68 is provided on the back side of the lower table 65. As well shown in FIG. 23, the pusher 68 is supported on the lower table 65 via rollers 69 arranged in front and rear thereof. As a result, the pusher 68 can reciprocate back and forth along the lower table 65. 19 to 24 show a state in which the pusher 68 is retracted. A pusher drive mechanism (not shown) drives the pusher 68 between a position shown in the figure and a position protruding forward. The pusher driving mechanism may use various mechanisms used in known pusher game machines, such as a mechanism that converts the rotation of the motor into a reciprocating motion of the pusher 68 by a slider crank mechanism.

  When the pusher 68 reciprocates back and forth, the medals that have fallen on the lower table 65 are struck, and a ball thrusting action occurs between the medals on the lower table 65. Depending on how the ball thrusting action occurs, the front edge 65a of the lower table 65 Or a medal falls from the side edge 65b (refer FIG. 20). The dropped medal is collected into a medal hopper device (not shown). The fall of the medal from the front edge 65a is detected by a medal drop sensor (not shown), and the medal is paid out from the medal hopper device to the medal tray 50 by the detected number.

  Next, details of the medal guidance device 63 will be described with reference to FIGS. 25 to 31. As shown in FIG. 25, the medal guide device 63 includes a guide block 70 and a drive mechanism 71 that drives the guide block 70. Details of the guide block 70 are shown in FIGS. The guide block 70 has a plurality of (10 in the figure) medal guide members 73 arranged on a common substrate 72 side by side at an equal pitch in a fixed direction. The medal guide member 73 is a resin molded product having a rectangular parallelepiped lower portion and a semi-cylindrical medal receiving surface 73a on the upper surface side. The synthetic resin used for the medal guide member 73 needs to have an appropriate friction resistance against the friction with the medal. For example, POM is preferably used as the material of the medal guide member 73. A protrusion 73 b is provided on the top of the medal guide member 73. The protrusion 73b extends along the axial direction of the medal receiving surface 73a, in other words, along the front-rear direction of the game board surface 43. However, the range in which the protrusion 73 b is provided is limited to the rear half of the medal guide member 73 in the front-rear direction of the game board surface 43. A gap 74 is provided between the medal guide members 73 on the substrate 72. These gaps 74 are somewhat larger than the thickness of the medal. The gap 74 may be a constant interval, but in this embodiment, the gap 74 gradually increases as the gap 74 approaches the checker 64. This is to prevent medals from clogging in the gap 74 when a plurality of medals fall into the gap 74 simultaneously.

  As shown in FIGS. 30 and 31, each medal guide member 73 is individually attached from the lower surface side of the substrate 72 using an attachment screw 75. Therefore, when a specific medal guide member 73 is dirty or damaged, only the medal guide member 73 can be removed from the substrate 72 and replaced. A base 76 is attached to the lower surface side of the substrate 72. The base 76 includes a support portion 76a that supports the guide block 70, and a connecting portion 76b that extends rearward from the support portion 76a. By tilting the support portion 76a forward and downward relative to the connecting portion 76b, the board 72 is inclined so as to form a downward slope toward the checker 64, and the medal guide member 73 also extends from the rear end portion 73c to the front end portion. It is inclined so as to gradually decrease toward 73d.

  As shown in FIGS. 25 to 28, a base frame 77 fixed to the housing 41, a slider 79 supported on the base frame 77 via a pair of guide rails 78 so as to be movable in the left-right direction, and a slider 79 And a motor 80 as a drive source. The rear end side of the slider 79 is folded downward, and a guide plate 81 is attached to the folded portion. The guide plate 81 is formed with a guide groove 81a extending in the vertical direction. On the other hand, a crank arm 82 is attached to the output shaft 80a of the motor 80 so as to rotate integrally with the output shaft 80a, and a crank pin 83 is attached to the tip of the crank arm 82. The tip of the crank pin 83 is inserted into the guide groove 81 a of the guide plate 81. Further, a guide block 70 is disposed above the base frame 77, and a connecting portion 76 b of the base 76 is connected to the slider 79.

  Therefore, when the output shaft 80a of the motor 80 is rotated in a certain direction, the movement is converted into the reciprocating movement of the slider 79 by the crankpin 83 and the guide plate 81, and the slider 79 and the base 76 are connected. The guide block 70 reciprocates left and right. As shown in FIG. 26, the gap 74 between the medal guide members 73 provided in the guide block 70 extends in the same direction as the medal passage hole 64 a of the checker 64. As shown in FIG. 28, the substrate 72 serving as the bottom of the gap 74 is disposed above the checker 64 and is tilted forward and downward toward the checker 64.

  With such a configuration, a medal inserted from the medal inserter 47 and rolled on the medal guide plate 67 falls on the medal receiving surface 73 a of the guide block 70. Since the medal receiving surface 73a is formed in a semi-cylindrical surface shape, the medal dropped there is guided to the gap 74 by sliding on the medal receiving surface 73a. As a result, the direction of the medals falling from the medal guide plate 67 toward the center side of the game board surface 43 is inclined slightly in the front-rear direction of the game board surface 43 (the direction in which the gap 74 extends). The medals guided to the gap 74 are erected in a state where their directions are aligned in the same direction as the medal passage hole 64a and roll down on the substrate 72. Further, since the protrusion 73b is provided on the top of the medal receiving surface 73a, even if a medal that has fallen from the guide plate 67 to the medal receiving surface 73a falls on its side, the medal comes into contact with the protrusion 73b. By doing so, the balance of the medals is lost, and there is no possibility that the medals are stabilized in a state where the medals have fallen sideways. Further, when the medal collides with the protrusion 73 b, the momentum of the medal is weakened, and the medal is surely dropped into the gap 74. Then, since the medal falls to the checker 64 through the gap 74, there is no possibility that the medal falls on the checker 64 in a sideways state. The effect of adjusting the direction of the medal by the protrusion 73b correlates with the length of the protrusion 73b. For example, if the protrusion 73b is shortened, the effect of the protrusion 73b is relatively reduced, and the frequency that the medal falls to the checker 64 while being in a lying state is increased. As a result, the probability that the medal enters the checker 64 is reduced. .

  By reciprocating the guide block 70 in the left-right direction by the drive mechanism 71, the match or mismatch of the positions of the gap 74 and the medal passage hole 64a is gradually switched in the left-right direction. If a medal falls to the checker 64 at a timing at which the gap 74 and the medal passage hole 64a substantially coincide, that is, they are connected in a straight line in the front-rear direction, the medal passes through the medal passage hole 64a. The medals that have fallen to the checker 64 at different timings are bounced by the checker 64 and fall to the lower table 65. As shown in FIG. 28, the checker 64 is provided with a guide rail 84 for guiding a medal that has passed through the medal passage hole 64a into the medal hopper.

  As described above, in the medal game machine according to the present embodiment, the medal guiding device 63 is arranged to align the medals inserted into the game board surface 43 in the same direction as the medal passage hole 64a of the checker 64 before passing the checker 64. Even a player who does not have sufficient skills can enjoy passing or not passing medals on the checker 64 as a game. Note that the substrate 72 and the medal guide member 73 of the medal guide device 63 are provided with a gradient opposite to that shown in FIG. 31, that is, a gradient that decreases toward the rear end 73c from the front end 73d of the medal guide member 73. The checker 64 may be disposed on the rear end portion 73 c side of the medal guide member 73.

  32 to 34 show details of the medal payout device 44. The medal payout device 44 is provided in order to pay a large amount of medals to the game board surface 43 at the time of a big hit or the like, and is extended so as to connect the left and right game board surfaces 43 to each other behind the medal plate 90. Belt conveyor 91, and shooter 92 disposed between both ends of belt conveyor 91 and upper table 62. The medal plate 90 is rotatably provided with a shaft portion 90a at the upper rear end as a fulcrum, and a leading end is lifted with a shaft portion 90a as a fulcrum by a standby position extending substantially horizontally from the shaft portion 90a by an actuator (not shown). It is driven between the operation position (position shown in FIG. 33 and FIG. 34). The actuator that drives the medal tray 90 may generate a rotational motion such as a motor, or may generate a linear motion such as a pneumatic cylinder. In the case of a rotational motion type actuator, the rotational motion may be transmitted around the shaft portion 90a to rotate the medal tray 90. In the case of a linear motion type actuator, the linear motion may be converted into the rotational motion of the medal tray 90 using a link mechanism or the like.

  A medal can be paid out from a medal hopper (not shown) to the medal tray 90. When the medal tray 90 is moved from the standby position to the operating position, the medal on the medal tray 90 falls onto the belt conveyor 91. Then, by moving the belt conveyor 91 in either the left or right direction, the medals on the belt conveyor 91 are conveyed to one of the shooters 92, and the medals are transferred to one of the upper tables 62 via the shooter 92. Can be paid out.

  As described above, since the belt conveyor 91 is disposed between the medal tray 90 and the shooter 92, the length of the shooter 92 can be shortened, and the shooter 92 is sufficiently inclined while suppressing the height of the medal tray 90. be able to. If the belt conveyor 91 is not used, a means for extending the shooter 92 to the center of the medal tray 90 in the left-right direction and directing the falling direction of the medal from the medal tray 90 to one of the shooters 92 is provided. In this case, however, if the shooter 92 is provided with a necessary and sufficient inclination, the overall height of the shooter 92 increases, and the position of the medal plate 90 must be changed upward accordingly. However, in that case, the total height of the subunit 3 is increased, and there arises a disadvantage that the monitor 6 and the lottery machine 7 of the main unit 2 behind are hidden. On the other hand, in the present embodiment, since the medals are horizontally conveyed to the immediate vicinity of each upper table 62 using the belt conveyor 91, the shooter 92 is shortened and the total height thereof is suppressed. For this reason, the position of the medal tray 90 can be lowered.

(Control system configuration)
Next, a control system of the game machine 1 will be described with reference to FIG. FIG. 35 is a block diagram of a control system provided in the main unit 2. The main unit 2 has a control device 100. The control device 100 is configured as a computer unit including a microprocessor, and is connected to a ROM 101 and a RAM 102 as main storage devices. In addition, a monitor 6 as a display device is connected to the control device 100, and a ball throwing mechanism 34, a drum drive motor 35, and an indicator drive mechanism 36 of the lottery machine 7 are connected as control target devices. Each mechanism is provided with one or a plurality of actuators, and the control device 100 is connected to each actuator via a drive circuit, but detailed illustration thereof is omitted.

  In order to exchange information between the main unit 2 and the subunit 3 and realize a predetermined game, the control device 100 of the main unit 2 is connected to the control system of each subunit 3. Further, a communication control device 103 is also connected to the control device 100 of the main unit 2. The communication control device 103 performs information communication via a predetermined communication line with the control device 100 of the main unit 2 of another game machine 1 to construct one game system in which a plurality of game machines 1 are assembled. Is provided to do. The main units 2 may be connected to each other via the communication control device 103 and the server, or the main units 2 may be connected to each other via the communication control device 103 without passing through the server. In addition to the above, various input devices and output devices may be connected to the control device 100 of the main unit 2. The other game machine 1 may be installed in the same store or may be installed in another store.

  FIG. 36 is a block diagram of a control system provided in the subunit 3. The subunit 3 also has a control device 110 configured as a computer unit with a microprocessor. The controller 110 is connected to a ROM 111 and a RAM 112 as main storage devices. The control device 110 is connected to a monitor 60 (see FIG. 19) as a display device. Furthermore, various devices provided in the left and right stations 40 are connected to the control device 110 as input devices or control target devices. For example, an operation switch 48 (see FIG. 13) and a winning detection sensor 113 are connected to the control device 110 as input devices. The winning detection sensor 113 detects a medal that has passed through the medal passage hole 64a of the checker 64 and is guided into the checker 64, and outputs a predetermined detection signal. The control device 110 includes a pusher drive motor 114 for driving the pusher 68, a motor 80 (see FIG. 25) for driving the guide block 70 of the medal guide device 63, and a housing 41 as control target devices. A medal hopper 115 for paying out medals is connected. FIG. 36 shows only the left station 40 in detail, but the same applies to the right station 40.

  Further, an actuator 116 for driving the medal tray 90 of the medal payout device 44 and a belt conveyor 91 are connected to the control device 110 of the subunit 3 as control target devices. The medal payout to the medal tray 90 is realized by the medal hopper 115, but may be realized by another medal hopper. In this case, a medal hopper different from the medal hopper 115 is connected to the control device 110 as a control target device corresponding to the medal tray 90.

  Further, a communication control device 117 is also connected to the control device 110 of the subunit 3. The communication control device 117 is provided for the control device 110 to perform information communication with the control device 100 of the main unit 2 of the same game machine 1. In addition to the above, various input devices and output devices may be connected to the control device 110 of the subunit 3. For example, in order to manage the payout rate of medals, a medal insertion sensor that detects the insertion of medals from the medal insertion unit 47, a medal drop detection sensor that detects the fall of medals from the lower table 65, and the like are connected to the control device 110. The

(Outline of the game)
The content of the game performed on the game machine 1 will be described with reference to FIGS. In addition to the basic game as a so-called pusher game in which the game machine 1 of the present embodiment is inserted from the medal inserter 47 and dropped onto the lower table 65 by pushing out the medal with the pusher 68, the checker 64 A game associated with winning a medal is provided to the player. FIG. 37 shows a game screen 200 displayed on the monitor 60 of the station 40 for such a game. The game screen 200 includes a main game unit 201, a roulette meter unit 202 disposed horizontally at the lower end of the screen 200, and a jackpot counter unit 203 disposed vertically at the left end of the screen 200.

  In the main game unit 201, the upper and lower three rows of symbol bands 201a to 201c are individually run like a reel of a slot machine, and when the symbol bands 201a to 201c are stopped at an appropriate timing, vertically or diagonally. A game for competing for the right or wrong of the specific winning combination is executed. The game of the main game unit 201 is executed with a medal winning to the checker 64 as a trigger. The symbols and winning combinations displayed on the main game unit 201 may be determined as appropriate, but are determined as shown in FIG. 38 as an example. Here, the probability variation means an operation for increasing the probability that a winning combination is established by a certain level. The center game is a game executed using the main unit 2, the single is given the right to play the center game only once, and the triple is played the center game three times in a row. Each means the right to

  FIG. 39 shows a game screen 300 displayed on the monitor 6 of the main unit 2 when the center game is executed, and FIG. 40 shows a game screen 301 displayed on the monitor of the station during the execution of the center game. As is clear from FIG. 39, a map 302 having an outer peripheral route 303 and an inner peripheral route 304 is displayed on the center game screen 300. Each route 303 is formed by connecting square cells 305 in a substantially square shape. In the figure, the cells 305 are distinguished by adding alphabets a, b, c,... The configurations of the routes 303 and 304 of the map 302 are stored as map information in the ROM 101 of the main unit 2.

  In the route 303 or 304, a piece 306 corresponding to each station 40 is displayed together with a station number (any one of 1 to 6). The game screen 301 in FIG. 40 is an enlarged view of the part of the game screen 300 where the piece 306 corresponding to the station 40 on which the screen 301 is displayed is located.

  When the right to play the center game in the game at the station 40 is granted, one of the numerical values 1 to 8 is drawn using the lottery machine 7 for the station, and the number of cells equal to the number obtained by the lottery Only the piece 306 moves on the route 303 or 304 in a certain direction. The contents of the reward given in the center game are described in each square 305. When the piece 306 stops, the reward described in the stopped square is given to the player who played the center game.

  For example, when the piece 306 stops on the cell 305a in which numerical values such as “30” and “50” are described, the player obtains a number of medals equal to the numerical value described there. The outer periphery route 303 has a square (hereinafter referred to as “SJP square”) 305b labeled “SJP chance”, and when the piece 306 stops there, the right to win the super jackpot is given. In this case, the lottery machine 7 is used to determine whether or not the super jackpot has been won. If the super jackpot is won, the player acquires the number of medals displayed on the SJP display unit 307 adjacent to the outside of the SJP mass 305b (hereinafter referred to as SJP number). Further, when the piece 306 passes through the SJP mass 305b, the SJP number is added by a predetermined number.

  On the other hand, the inner peripheral route 304 has a square (hereinafter referred to as a BB square) 305c labeled “BB chance”. When the piece 306 stops here, the right to win the big bonus is given. In this case, the lottery machine 7 is used to determine whether or not the big bonus has been won. If the big bonus is won, the player obtains the number of medals displayed on the BB display unit 308 arranged at the center of the inner route 304 (hereinafter referred to as the BB number). When the piece 306 passes through the BB cell 305c, a predetermined number of BBs are added.

  Warp masses 305d labeled “GO” are arranged at the four corners of each of the routes 303 and 304. When the piece 306 stops at the warp mass 305d, the piece 306 moves between the outer peripheral route 303 and the inner peripheral route 304. As can be understood by comparing the numerical values displayed on the square 305 a between the routes 303 and 304, the inner peripheral route 304 is easier to obtain a higher payout than the outer peripheral route 303. In addition to the above, privileged masses 305e, f... Are appropriately provided on the routes 303 and 304, but they are not the gist of the present invention, and thus the description thereof is omitted.

  When a plurality of game machines 1 are connected to each other to form one game system, the above-described inner peripheral route 304 is shared between the game machines 1. That is, the information regarding the structure of the inner periphery route 304 memorize | stored in ROM101 of each game machine 1 in one game system is mutually equal. In addition, the positions of the pieces 306 arranged on the inner peripheral route 304 and the number of BBs are shared between the game machines 1. These pieces of information are stored as information in the RAM 102 of the game machine 1, but the information is appropriately exchanged between the game machines 1 to maintain consistency.

  Then, a piece 309 in another game machine 1 is also displayed on the inner peripheral route 304. When these pieces 309 stop at the BB cell 305c, the right to win the big bonus is given to the station 40 of the game machine 1 corresponding to the piece 309. When the piece 309 passes through the BB cell 305c, a predetermined number of BBs are added to all the game machines 1 in the same game system. That is, the number of BBs has a character as a so-called progressive bonus shared among a plurality of game machines 1.

  In this way, a part of the map 302 is shared between a plurality of game machines 1, and a game payout in the shared part is also correlated between the game machines 1, so that the player can play the same game machine 1. It becomes necessary to care not only about other players but also about the game situation of the players of other game machines 1, and the interest in the game is increased. Further, since the common payouts are accumulated among the plurality of game machines 1, it is possible to generate a larger payout as compared with the case where the game payouts are accumulated only with a single game machine, and the game is also interesting. Can be increased.

(About control procedure)
When the station control routine is started, the control device 110 first performs a lottery using random numbers for combinations of symbols to be displayed on the main game unit 201 of the game screen 200 in step S101, and displays the lottery result. The display content of the gaming unit 201 is controlled. Specifically, the display contents are controlled so that each of the symbol bands 201a to 201c travels and a combination of symbols determined by lottery is obtained.

  Next, in step S102, it is determined whether or not a probability change starting combination (excluding “777”) is established. If a probability change starting combination is established, the probability variation flag is set to 1 in step S103. Proceed to step S106. On the other hand, when the probability variation starting combination is not established, the process proceeds to step S104, and it is determined whether or not the probability variation end combination is established, and when established, the probability variation flag is reset to 0 and the processing proceeds to step S106. move on. The probability variation flag is considered in the lottery in step S101, and when the flag is set to 1, the probability that a winning combination (the combination shown in FIG. 38) is established is higher than when the flag is reset to 0.

  In step S106, the medal hopper 115 is driven to pay out the number of medals corresponding to the winning combination in the lottery from the medal payout opening 61 to the upper table 62. At this time, an image in which the medals are swung may be performed by displaying an image of the medals falling on the monitor 6 and paying out the medals from the medal payout opening 61 in synchronization therewith.

  After the medal is paid out, the process proceeds to step S107, and 1 is added to the value of the JP step stored in the RAM 112. The value of the JP step is equal to the number of lighting of the jackpot counter unit 203 on the game screen 200. When the value of the RAM 112 is updated, the number of lighting of the jackpot counter unit 203 is also updated accordingly. In subsequent step S108, it is determined whether or not the JP step has reached a predetermined maximum value (7 in this case). If the maximum value is reached, JP is established and the process proceeds to step S109, where the upper table 62 is driven in the horizontal position → actuation position → horizontal position to drop all the medals accumulated on it to the medal guide device 63. A jackpot medal is paid out toward the lower table 65. At this time, medals may be paid out from the medal payout opening 61. Thereafter, in step S110, the JP step on the RAM 112 is reset to the initial value 0, and the station control routine ends.

  On the other hand, if the condition in step S104 is negative, the process proceeds to step S111 to determine whether or not a center game single combination (see FIG. 38) has been established. If it is established, the process proceeds to step S112, and the establishment of the main game single combination is notified to the control device 100 of the main unit 2. Thereafter, the process proceeds to step S106, and a medal corresponding to the center game single role is paid out.

  If the condition in step S111 is negative, the process proceeds to step S113, and it is determined whether or not a center game triple combination is established. If it is established, the process proceeds to step S114, and the upper table 62 is driven in the order of horizontal position → operation position → horizontal position. In subsequent step S115, the control device 100 of the main unit 2 is notified of the establishment of the main game triple combination. Thereafter, the process proceeds to step S103, where 1 is set in the probability variation flag, and then the process proceeds to step S106, where a medal corresponding to the center game triple combination is paid out.

  If the triple combination is not established in step S113, the process proceeds to step S116, and does the roulette symbol (the symbol shown in the second row from the bottom in FIG. 38) exist in the main gaming unit 201 after the symbol bands 201a to 201c are stopped? Judge whether or not. If it exists, the process proceeds to step S117, and 1 is added to the value of the roulette meter stored in the RAM 112. The value of the roulette meter is equal to the number of lighting of the roulette meter unit 202 of the game screen 200. When the value of the RAM 112 is updated, the number of lighting of the roulette meter unit 202 is updated accordingly. In subsequent step S118, it is determined whether or not the roulette meter value has reached a predetermined maximum value (25 in this case). If the maximum value has been reached, the process proceeds to step S119 to notify the control device 100 of the main unit 2 that the center game single combination has been established. Thereafter, in step S120, the roulette meter value on the RAM 112 is reset to the initial value 0, and the station control routine is finished.

  If it is determined in step S116 that there is no roulette symbol, or if it is determined in step S118 that the meter value is not the maximum value, the subsequent processing is skipped and the station control routine is terminated.

  Next, processing of the control device 100 of the main unit 2 will be described. 42 and 43 show a center game control routine executed by the control device 100 of the main unit 2 to realize the center game. When the establishment of the center game single role or triple role is notified from the control device 110 of any one subunit 3, this routine is executed for the station 40 that has established the single role or triple role. . That is, the following processing is executed with respect to the station 40 that has established the center game single role or triple role unless otherwise specified.

  When the center game control routine is started, the control device 100 first determines whether or not a single combination is notified in step S200. When the single combination is notified, the process proceeds to step S201, and the initial value 1 is set to the variable N for determining the number of games. When the single combination is not notified (that is, when the triple combination is notified). In step S202, the initial value 3 is set in the variable N. After the variable N is set, the process proceeds to step S203, and the roulette lottery, that is, the lottery of any one of 1 to 8 using the lottery machine 7 is executed. Then, the position information of the piece 306 stored in the RAM 102 is updated so that the position of the piece 306 on the map 302 advances by the number of cells equal to the obtained numerical value. The position information of the piece 306 is stored in the RAM 102 in association with information for identifying the station 40. The position information updated at this time relates to the piece 306 corresponding to the station 40 that has established the center game single role or triple role. Is. The display on the monitor 6 is also updated in response to the update of the frame position information.

  In the following step S204, it is determined whether or not the piece 306 has passed the SJP cell 305b. Proceed to step S208. On the other hand, if the SJP cell 305b is not passed in step S204, the process proceeds to step S206, and it is determined whether or not the piece 306 has passed the BB cell 305c. If it passes through the BB cell 305c, the process proceeds to step S207, and the BB number is increased by a predetermined number. Further, since the number of BBs is shared with other game machines 1 constituting the same game system, the addition of the number of BBs is also notified to the control device 100 of those game machines 1. After these processes, the process proceeds to step S208. If a negative determination is made in step S206, step S207 is skipped and the process proceeds to step S208.

  In step S208, the type of square (stop square) corresponding to the frame position updated in step S203 is determined. In the subsequent step S209, it is determined whether or not the piece 306 has stopped on the SJP square 305b. If it has stopped, the process proceeds to step S210 to perform a roulette lottery regarding the super jackpot. In this case, the roulette lottery is performed, for example, by using one of the eight sections displayed on the drum 31 of the lottery machine 7 as a super jackpot (SJP) winning box. Of course, the lottery may be performed by other means. After waiting for the roulette (drum 31) to stop, the process proceeds to step S211, and it is determined whether or not the super jackpot is won. If it has been won, the process proceeds to step S216. If not, the process proceeds to step S220 in FIG. In step S220, the number of medals corresponding to the numerical value obtained by the roulette lottery in step S210 or S213 is set to the number acquired by the player.

  On the other hand, when it is determined in step S209 in FIG. 42 that the SJP box 305b is not stopped, the process proceeds to step S212, and it is determined whether or not the piece 306 is stopped on the BB box 305c. If it has stopped, it will progress to step S213 and will perform the roulette lottery regarding a big bonus. The roulette lottery in this case is also performed, for example, as one of the eight sections displayed on the drum 31 of the lottery machine 7 as a big bonus (BB) winning box. Of course, the lottery may be performed by other means. After waiting for the roulette (drum 31) to stop, the process proceeds to step S214, and it is determined whether or not the big bonus is won. If it has been won, the process proceeds to step S215, the winning of the big bonus is notified to other game machines 1 included in the same game system, and the process proceeds to step S216. Note that the processing in steps S204 to S209 and S212 can be performed immediately after the roulette lottery result is obtained in step S203, and the display on the monitor 6 is updated according to the result obtained in step S203. There is no need to wait.

  In step S216, the number of medals corresponding to SJP or BB is paid out. The payout at this time is performed on the medal tray 90 of the medal payout device 44. Accordingly, the control device 100 instructs the control device 110 of the subunit 3 to pay out medals, and in response to this, the control device 110 waits for the completion of the payout of medals to the medal plate 90 and moves the medal plate 90 to the operating position. Drive, wait for the medal to fall on the belt conveyor 91, and then run the belt conveyor 91 toward the station 40 on the side winning SJP or BB. Payout to the upper table 62 of the station 40.

  After paying out SJP or BB, the process proceeds to step S217, the SJP number or BB number stored in the RAM 102 is reset to the initial value, and the center game control routine ends. If the stop to the BB cell 305c is denied in step S212, the process proceeds to step S221 in FIG.

  In step S221 in FIG. 43, it is determined whether or not the piece 306 has stopped at the warp mass 305d. If the warp mass 305d is not stopped, the process proceeds to step S222, and it is determined whether or not the piece 306 is stopped at another privilege mass 305e, 305f. If the piece 306 is stopped on the normal square 305a, step S222 is denied, and in this case, the process proceeds to step S223, and the numerical value written on the stopped square 305a is set as the acquired number. On the other hand, when the condition of step S222 is affirmed, the process proceeds to step S224, and a process corresponding to the winning content assigned to the privilege mass 305e is executed.

  After the acquired number is set in step S220 or S223, the process proceeds to step S225, and medals are paid out by the acquired number. In this case, the medal payout device 44 may be used to pay out medals. However, when the number is small, it may be paid out from the medal payout opening 61. When the warp mass 305d is stopped in step S221, the process proceeds to step S227, and the piece 306 is moved between the warp mass 305d of the outer peripheral route 303 and the warp mass 305d of the inner peripheral route 304. The condition may be changed between the movement from the outer periphery route 303 to the inner periphery route 304 and the movement from the inner periphery route 304 to the outer periphery route 303. For example, the movement in the reverse direction may be limited as compared with the movement from the inner route 304 to the outer route 303.

  After the process of step S224, S225, or S227, the process proceeds to step S226, and the updated stop position of the piece 306 is notified to the other game machines 1. However, the notification may be targeted only for the piece 306 located on the inner peripheral route 304. After notification of the stop position, the process proceeds to step S228, and it is determined whether or not the variable N is 1. If it is not 1, the process proceeds to step S229 where 1 is subtracted from the variable N, and then the process returns to step S203 in FIG. If the variable N is 1 in step S228, the center game control routine ends.

  FIG. 44 shows a game information update control routine executed by the control device 100 in order to share the number of BBs and the positions of the pieces 306 and 309 on the inner peripheral route 304 with other game machines 1. This process is repeatedly executed in the controller 100 at an appropriate cycle. In the game information update control routine, the control device 100 first determines whether or not the addition of the BB number is notified from another game machine 1 in step S250. If notified, the process proceeds to step S251, and the number of BB held in the RAM 102 is updated to a value increased by a predetermined number. If not notified, step S251 is skipped. In a succeeding step S252, it is determined whether or not BB winning is notified from another game machine 1. If notified, the process proceeds to step S253, and the number of BBs held in the RAM 102 is reset to the initial value. If not notified, step S253 is skipped.

  In a succeeding step S254, it is determined whether or not the stop position of the piece 306 is notified from another game machine 1. If notified, the process proceeds to step S255, and the position information of the piece 309 on the inner peripheral route 304 held in the RAM 102 is updated according to the notified content. If not notified, step S255 is skipped. In the subsequent step S256, the number of BBs and the display content of the map 302 are updated according to the latest content stored in the RAM 102. Thus, the game information update control routine is completed.

  44 is repeatedly executed as appropriate, the number of BBs held in the RAM 102 of each game machine 1 and the piece position information on the inner peripheral route 304 can be maintained in an equal state.
